Stethoscopes are indispensable tools for clinicians and are widely used, in particular, for medical and pediatric disease diagnosis and treatment. However, for pediatricians, crying and screaming are common and heart rate auscultation is difficult due to the uncooperative condition of the children. A stethoscope that can display heart rate would be a gospel for pediatricians.
The utility model discloses improve ordinary stethoscope, design a section stethoscope that can show the rhythm of the heart. Compared with the existing stethoscope, the stethoscope has the advantages that: the heart rate can be directly displayed, and the auscultation of the infants is facilitated.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a stethoscope that can show rhythm of the heart to the infant who proposes in solving above-mentioned background does not cooperate, and the phenomenon of crying is common, rhythm of the heart auscultation difficulty scheduling problem, and the stethoscope that can show the rhythm of the heart that proposes.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a stethoscope that can show rhythm of heart, includes earphone, rubber buffer, three way connection ware, rubber connection pipe and stethoscope probe, its characterized in that: lie in the earphone is connected on the rubber plug, the rubber buffer is connected on three way connection ware, three way connection ware's below fixed connection rubber connecting pipe, the downside fixed connection stethoscope probe of rubber connecting pipe, the stethoscope probe comprises two cylinders of variation in size, the lower surface mounting of stethoscope probe has the piezoelectric type sensor, it installs the battery to open there is the recess on the piezoelectric type sensor, the cylindrical internally mounted of upside of stethoscope probe has microprocessor, the last surface mounting of stethoscope probe has liquid crystal display.
Preferably, the earphone is an in-ear earphone, so that a stethoscope can clearly hear the heart rate of a patient.
Preferably, both connectors on the upper side of the three-way connector are connected to the earpiece, and the connector on the lower side of the three-way connector is connected to the rubber connecting pipe.
Preferably, the rubber connecting pipe is made of a rubber material, so that the weakening of the vibration signal can be reduced to a certain extent.
Preferably, the stethoscope probe is provided with a piezoelectric sensor at the edge thereof for collecting mechanical vibration of cardiac contraction.
Preferably, the high-sensitivity sensor, the microprocessor and the liquid crystal display are electrically connected with a battery, and the systolic vibration is converted into an electric signal and is displayed on the liquid crystal display in a digital form.
Preferably, the piezoelectric sensor is in the MD30-60 series.
Compared with the prior art, the beneficial effects of the utility model are that: can direct display rhythm of the heart, make things convenient for infant's auscultation, the in-ear earphone can make the accurate patient rhythm of the heart of hearing of doctor to a certain extent, and the judgement of doctor simultaneously and the judgement patient's that the digit on the LCD can be more accurate rhythm of the heart, prevents the misdiagnosis.
